Just got my first dedicated radio pc, the video card produces a heap of hash on many of the HF bands. Have reduced it a bit by winding many turns round some ferrite rods, but there is still a continual set of noises at about 18khz intervals, frankly its driving me nuts.

As I change the resolution its gets worse as it goes higher, so down to lower res 800 x 600 and 16 colours, and its passable just, but still thee on most bands.

Any ideas please.

No pencil and paper does not count. Thanks

Will try another display over that side of the room. One side is the office and the other side is radio. It was a freebie PC and ACER LED display, so its a no cost setup. Am going to try and find my power line filter today and put that into the monitor lead.

Sort of retribution isn't it reverse TVI.
